Letters Patent No. 78,571, dated June 2, 1868.

IMPROVEMENT IN SHAITGOUPLING.

TO ALL WHOM IT MAY OONOERN:

Be it known that I, LEVI BRONGON, of Bu'alo, in the county ot'Erie, and State of New York, have invented a certain new and 'useful Improvement in ShattOouplings; and Ido hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making-part of this specification, in whieh- Figure 1 is a plan of the ring.

Figure 2, a perspective-view', showing the shutting detached from the ring.

Figure 3 is an edge View ofthe ring.

Like letters of reference indicate corresponding parts in all thegures.

Myinvention consists in providing the ring with guards, and employing, in combination therewith, headless bolts, keyed in place, for holding the sections of the shafting.

In the drawings, A represents the coupling-ring, and Bits outer circular rim, provided with right-angled flanges or guards, C C, raised on its edge on opposite sides. D D, are headless bolts, which pass through raised bearings, a-a, at right angles with eachother, and secure the forks?) of the ordinary sections of shafting E, which are shown detached in fig. 2. One ond of these bolts comes in Contact with the flanges C, which prevent their dropping out or protruding beyond the ring, and .they are held from slipping out by keys, p 7o. v

The great advantage of this arrangement consists in the guards C with the headless bolts D. The ring is cast inA a single piece, of openform, with the guards constituting a part of it, the latter serving not only to keep the bolts in place against end movement, but also as a shield to, prevent contact therewith. '.lhus, there is no danger of the clothing .or other articles coming in Contact, and winding up. By this construction, also, I am enabled to make the bolts D D headless, being retained in place against end movement in one direction by the guards, and in the other by the keys pp.

I am aware that headless bolts have before been used in connection with a wide ,cylindrical ring, in which the bolts are inserted by bayonet-slots, or other indirect communica-tion. i

In such cases the construction is complicated and expensive. In my invention the device is exceedingly cheap and simple. The bolts are entered in the bearings a a directly,v and without any trouble, and, at the same time, are perfectly locked in place, and an efl'ective shield is produced to prevent accident.

With my invention, shafting can be coupled and uncouplecl with less trouble than by any other device that I am acquainted with.

What I claim as luy-invention, und desire to secure by Letters Patent, is'- The guard-flanges C C of ring A, in combination with the forked shutting E, headless bolts D D, held by keyspln' the whole arranged as described, and operating in the manner and for the purpose set`forth.

In .witness whereof, I have hereunto signed my name, in the presence of two subscribing witnesses.

LEVI BRONSON.
